In 1984, under the guidance of Archbishop Iakovos, Leadership 100 was created as an endowment fund of the Greek Orthodox Archdiocese through which Greek Orthodox leaders were asked to commit themselves to offer $10,000 a year for a total of $100,000 each to maintain the life-sustaining ministries of the Church.

Leadership 100 grants have been instrumental in seeding and nurturing such organizations as the International Orthodox Christian Charities (IOCC) and the Orthodox Christian Mission Center (OCMC), and have been the mainstay of support of Holy Cross School of Theology, providing scholarships that have prepared young men for the Priesthood. Grants also have supported Clergy, Youth, Young Adult and Camping Ministries, a technology infrastructure and Internet Ministries at the Greek Orthodox Archdiocese of America, Religious and Greek Education, Interfaith Marriage and Family Ministries, as well as critical needs in addressing crises such as September 11, Hurricane Katrina, fires in Greece, and Hurricane Sandy.

With the initial membership of 100 soon surpassed, Leadership 100 “raised the bar” and grew progressively to 300, doubling its membership to 600 in 2000 and now to more than 900 members in 2013, including 118 Leadership 100 Partners and Junior Partners, young professionals who progress in their contributions as they progress in their careers. The membership includes a broad spectrum of Greek Orthodox leaders, men and women of all ages from every field.

Leadership 100 is a driving force to seed and nurture new programs that advance Orthodoxy and Hellenism into the 21st Century.
